[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] A breast pump is a tool used to squeeze out breast milk accumulated in the mammary gland. In order to help unclog the mammary gland, some heated breast pumps are available on the market. The speaker cover of the heated breast pump that contacts the breast is usually provided with a heating element, and a control host is provided to control the heating element to heat so as to achieve a hot compress function. The hot compress function helps to increase the amount and speed of milk production of the mother. However, the breast pump usually needs to be boiled or steamed after use. During this process or during the process of sucking and pouring milk, water or milk can easily enter the speaker cover and the control host and cause damage to the contact points or short circuits. In order to solve the above problems, the present application proposes the following embodiments.

[0031] The following is an exemplary description of a breast pump according to a breast pump embodiment.

[0032] like Figure 1 and Figure 2 As shown, the breast pump 1 may include a horn cover 10 , a milk bin 30 and a host 20 .

[0033] The milk bin 30 can be sealedly connected to the horn cover 10 to enclose the horn cover 10 to form a milk storage cavity 40 .

[0034] Alternatively, if Figures 2 to 4 As shown, the speaker cover 10 may include a cover body 110, a heating element 120 and a first terminal assembly 130, the heating element 120 and the first terminal assembly 130 may be disposed on the cover body 110, and the first terminal assembly 130 and the heating element 120 may be electrically connected. The host 20 may include a main body 210 and a second terminal assembly 220 disposed on the main body 210, and the second terminal assembly 220 is used to electrically contact the first terminal assembly 130 when the main body 210 and the cover body 110 are assembled.

[0035] The speaker cover 10 can be buckled onto the nipple and areola to fit the human breast to collect breast milk. The host 20 can control the speaker cover 10 to apply negative pressure to the nipple through the first terminal assembly 130 and the first terminal assembly 130 to stimulate the nipple to produce milk, thereby collecting breast milk into the milk storage cavity 40.

[0036] Furthermore, the host 20 can also control the heating element 120 through the first terminal assembly 130 and the second terminal assembly 220 , so that the heating element 120 can be controlled by the host 20 to heat the cover 110 , and then heat the human body through the cover 110 .

[0037] Among them, Figures 2 to 7 As shown, the milk bin 30 includes a partition wall 310 sandwiched between the cover 110 and the main body 210, and the partition wall 310 is provided with an electrode through hole 311. When the main body 210 and the cover 110 are assembled to the milk bin 30, the first terminal assembly 130 and the second terminal assembly 220 are in electrical contact through the electrode through hole 311.

[0038] The breast pump 1 may be provided with an annular sealing portion 50 , which seals and surrounds the periphery of the first terminal assembly 130 and the second terminal assembly 220 .

[0039] Optionally, the annular sealing portion 50 may be waterproof soft silicone, which can prevent the penetration of liquids such as water or milk, so that the annular sealing portion 50 can form an enclosed space with the host 20, thereby sealing the connection position of the first terminal assembly 130 and the second terminal assembly 220.

[0040] By setting an annular sealing portion 50 between the cover body 110 and the main unit 20, and setting the annular sealing portion 50 to seal around the periphery of the first terminal assembly 130 and the second terminal assembly 220, the connection between the first terminal assembly 130 and the second terminal assembly 220 is placed in a closed environment, thereby making it difficult for liquids such as moisture or milk to penetrate into the connection between the first terminal assembly 130 and the second terminal assembly 220 and further enter the interior of the speaker cover 10 and the main unit 20, thereby ensuring the conductive contact stability between the first terminal assembly 130 and the second terminal assembly 220, and making it difficult for the speaker cover 10 and the main unit 20 to be short-circuited or damaged, thereby improving the safety of the breast pump 1.

[0041] In some embodiments, Figures 2 to 4As shown, the annular sealing portion 50 may be located on the cover 110, and the annular sealing portion 50 may surround the periphery of the first terminal assembly 130. The annular sealing portion 50 may be used to abut the main body 210 and further surround the periphery of the second terminal assembly 220 when the main body 210 and the cover 110 are assembled on the milk bin 30. Optionally, the main body 210, the cover 110 and the milk bin 30 may be a detachable assembly structure. When the main body 210, the cover 110 and the milk bin 30 are assembled, the main body 210 abuts against the annular sealing portion 50 of the cover 110, so that the main body 210 and the annular sealing portion 50 can form a closed structure. Moreover, the annular sealing portion 50 surrounds the periphery of the first terminal assembly 130 and the second terminal assembly 220 and abuts the main body 210, so the annular sealing portion 50 can seal the connection between the first terminal assembly 130 and the second terminal assembly 220, thereby improving the sealing effect of the breast pump 1. Moreover, the detachable structure can improve the assembly efficiency of the breast pump 1, facilitate the assembly and disassembly of the breast pump 1, and also make it easier for the main body cover 110 and the annular sealing portion 50 to achieve a sealing structure at the connection between the first terminal assembly 130 and the second terminal assembly 220.

[0042] Optionally, the cover body 110 may be integrally formed, and the annular sealing portion 50 may be formed on the cover body 110, so that the annular sealing portion 50 can be more firmly arranged. Optionally, the cover body 110 may be made of soft silicone as a whole, and the cover body 110 may be formed by injection molding. Injection molding may make the formation of the cover body 110 and the annular sealing portion 50 simpler, and make the size of the annular sealing portion 50 finer, so as to improve the sealing effect of the breast pump 1.

[0043] In some embodiments, Figure 3 As shown, the first terminal assembly 130 may have a contact portion 131 for electrically contacting the second terminal assembly 220. In the electrical contact direction from the first terminal assembly 130 to the second terminal assembly 220, the annular sealing portion 50 may be closer to the body 210 than the contact portion 131. Figure 3 In the direction indicated by the arrow in B.

[0044] In other words, in the electrical contact direction from the first terminal assembly 130 to the second terminal assembly 220, the annular sealing portion 50 can be raised compared to the contact portion 131 of the first terminal assembly 130, so that the annular sealing portion 50 can provide a residual abutment against the main body 210, so that during the assembly process, the annular sealing portion 50 can be more effectively pressed against the main body 210, and the main body 210 can press the annular sealing portion 50, and the pressed annular sealing portion 50 can compact the gap between the host 20 and the cover body 110, thereby forming an enclosed space, thereby sealing the contact portion 131 of the first terminal assembly 130.

[0045] In some embodiments, Figure 3 As shown, the first terminal assembly 130 can extend into the electrode through hole 311 or pass through the electrode through hole 311 when the main body 210 and the cover body 110 are assembled in the milk bin 30 , and the annular sealing portion 50 is located outside the electrode through hole 311 to abut against the main body 210 .

[0046] Optionally, the first terminal assembly 130 can be in electrical contact with the second terminal assembly 220 inside the electrode through hole 311 or outside the electrode through hole 311. The annular sealing portion 50 is located outside the electrode through hole 311 and is pressed against the main body 210.

[0047] In some embodiments, Figures 2 to 5 As shown, the cover body 110 may include an elastic covering portion 111 , and the elastic covering portion 111 may surround and cover the outer circumference of the first terminal assembly 130 . The elastic covering portion 111 may form an annular sealing portion 50 toward one end of the main body 210 .

[0048] Specifically, the elastic covering portion 111 is arranged on the periphery of the first terminal assembly 130, so that the elastic covering portion 111 can protect the first terminal assembly 130, and when the main body 210 presses the annular sealing portion 50 formed by the elastic wrapping portion 111, the elastic covering portion 111 can seal the first terminal assembly 130, thereby preventing liquids such as moisture and emulsion from contacting the first terminal assembly 130 and damaging the first terminal assembly 130.

[0049] Alternatively, if Figures 3 to 7 As shown, the partition wall 310 may abut against the outer peripheral wall of the elastic covering portion 111 , so that the partition wall 310 and the elastic covering portion 111 are mutually limited, thereby improving the structural stability and tightness of the breast pump 1 .

[0050] In some embodiments, Figures 3 to 7 As shown, an annular sealing rib 1111 and an annular sealing groove 312 are provided on the outer peripheral wall of the elastic covering portion 111 along its circumferential direction, and an annular sealing rib 1111 and an annular sealing groove 312 are provided on the hole wall of the electrode through hole 311 of the partition wall 310 along its circumferential direction, and the annular sealing rib 1111 is sealed and embedded in the annular sealing groove 312.

[0051] For example, an annular sealing rib 1111 may be provided on the outer peripheral wall of the elastic covering portion 111, and an annular sealing groove 312 may be provided on the wall of the electrode through hole 311 along its circumference of the partition wall 310, and the annular sealing rib 1111 and the annular sealing groove 312 are mutually engaged and buckled, so that the elastic covering portion 111 and the partition wall 310 are mutually limited to achieve a fixed connection, so that the elastic covering portion 111 and the partition wall 310 are not easily separated from each other in the opening direction of the electrode through hole 311. The opening direction of the electrode through hole 311 may be consistent with the electrical contact direction from the first terminal assembly 130 to the second terminal assembly 220.

[0052] Moreover, the elastic covering portion 111 has a certain elasticity. Therefore, when the elastic covering portion 111 and the partition wall 310 are engaged and fastened with each other through the annular sealing rib 1111 and the annular sealing groove 312, the annular sealing rib 1111 can press against the partition wall 310 in the electrode through hole 311, thereby achieving sealing, so that liquids such as moisture and breast milk are not easy to enter the interior of the speaker cover 10 and the main unit 20 through the gap between the elastic covering portion 111 and the partition wall 310, thereby achieving double sealing together with the sealing structure of the annular sealing portion 50 to improve the electrical safety of the breast pump 1.

[0053] In some embodiments, Figures 2 to 7 As shown, the elastic covering portion 111 may be formed with a through hole 112. The elastic covering portion 111 is sleeved on the outer periphery of the first terminal assembly 130 through the through hole 112. Such a configuration can limit the elastic covering portion 111 and the first terminal assembly 130 to each other in the through direction of the through hole 112. The through direction of the through hole 112 can be as follows: Figure 3 Indicated by the arrow in B.

[0054] Optionally, the direction of the through hole 112 can be the electrical contact direction from the first terminal assembly 130 to the second terminal assembly 220. In this direction, since the elastic covering portion 111 forms a contact portion 131 that is higher than the electrical contact between the first terminal assembly 130 and the second terminal assembly 220, the first terminal assembly 130 can contact the second terminal assembly 220 in the through hole 112.

[0055] Such a configuration can enable the elastic covering portion 111 to better protect the first terminal assembly 130, and can also make the connection between the elastic covering portion 111 and the first terminal assembly 130 tighter. The elastic covering portion 111 can further limit the position of the first terminal assembly 130, so that the first terminal assembly 130 is not easily displaced, thereby ensuring the connection stability between the first terminal assembly 130 and the second terminal assembly 220, and also ensuring the sealing stability between the first terminal assembly 130 and the second terminal assembly 220.

[0056] In some embodiments, Figures 2 to 7 As shown, the heating element 120 can be disposed inside the cover 110 , the through hole 112 can communicate with the inside of the cover 110 , and the first terminal assembly 130 can be disposed on the heating element 120 and extend from the inside of the cover 110 through the through hole 112 to the outside of the cover 110 .

[0057] Such a configuration allows the elastic covering portion 111 to wrap and seal the first terminal assembly 130 in the through hole 112 , while further preventing moisture from entering the cover body 110 through the through hole 112 and damaging the heater 120 or causing a short circuit in the heater 120 .

[0058] In some embodiments, the elastic covering portion 111 may be provided with at least one of a limiting groove 132 and a limiting protrusion 1112 on the hole wall of the through hole 112, and at least the other of the limiting groove 132 and the limiting protrusion 1112 may be provided on the outer peripheral wall of the first terminal assembly 130, and the limiting protrusion 1112 is embedded in the limiting groove 132, so that the elastic covering portion 111 and the first terminal assembly 130 limit each other in the penetration direction of the through hole 112. Optionally, the first terminal assembly 130 and the elastic covering portion 111 are tightly matched.

[0059] For example, Figures 2 to 5 As shown, the elastic covering portion 111 can be provided with two circles of limiting protrusions 1112 on the hole wall of the through hole 112, and the outer peripheral wall of the first terminal assembly 130 can be provided with two circles of limiting grooves 132 corresponding to the hole wall of the through hole 112. The first terminal assembly 130 and the elastic covering portion 111 can be tightly fitted, and the two circles of limiting protrusions 1112 are embedded in the two circles of limiting grooves 132, so that the elastic covering portion 111 and the first terminal assembly 130 can be tightly fitted, thereby limiting each other.

[0060] Of course, in another embodiment, the elastic covering portion 111 can be provided with a limiting groove 132 and a limiting protrusion 1112 on the hole wall of the through hole 112, and the outer peripheral wall of the first terminal assembly 130 can also be provided with a limiting protrusion 1112 and a limiting groove 132 corresponding to the hole wall of the through hole 112, and the limiting grooves 132 and the limiting protrusions 1112 on both sides correspond to each other one by one, thereby realizing multiple limits.

[0061] Through the above configuration, the connection tightness and stability between the elastic covering portion 111 and the first terminal assembly 130 can be improved, and the elastic covering portion 111 and the first terminal 134 can be prevented from being separated from each other in the penetration direction of the through hole 112, and the sealing effect of the elastic covering portion 111 can be further enhanced.

[0062] In some embodiments, Figure 3As shown, the main body 210 may be provided with a receiving cavity 230 and a receiving hole 240 connected to the receiving cavity 230 , and a portion of the second terminal assembly 220 is disposed in the receiving cavity 230 and penetrates through the receiving hole 240 , extending out of the main body 210 through the receiving hole 240 .

[0063] Alternatively, if Figure 3 As shown, the accommodating cavity 230 of the main body 210 may include other control elements. For example, the accommodating cavity 230 of the main body 210 may include a circuit board 250, and the circuit board 250 may include a processing element such as a processor.

[0064] The receiving hole 240 can be opened on the housing 211 of the main body 210 in the direction of the circuit board 250 facing the cover body 110, and the receiving cavity 230 is between the circuit board 250 and the housing 211 of the main body 210. One end of the second terminal assembly 220 is electrically connected to the circuit board 250 in the receiving cavity 230, and the other end extends toward the receiving hole 240 and passes through the receiving hole 240 to electrically contact the first terminal assembly 130. The circuit board 250 is then electrically connected to the heating element 120 through the second terminal assembly 220 and the first terminal assembly 130 in contact with the second terminal assembly 220, and then the heating element 120 can be controlled to heat.

[0065] In some embodiments, Figure 3 As shown, the host 20 may include a sealing gasket 260 , which may be disposed in the accommodating cavity 230 and surround the outer periphery of the second terminal assembly 220 , and abut between two opposite cavity walls of the accommodating cavity 230 to seal the accommodating hole 240 .

[0066] Optionally, the sealing gasket 260 fits tightly to the outer periphery of the second terminal assembly 220, and in the extension direction of the second terminal assembly 220, one end of the sealing gasket 260 abuts against a wall of the accommodating cavity 230 facing the accommodating hole 240, that is, abuts against the circuit board 250, and the other end abuts against the cavity wall of the accommodating cavity 230 to seal the accommodating hole 240.

[0067] Such arrangement enables the sealing gasket 260 to seal the receiving hole 240 at one end of the receiving hole 240 close to the circuit board 250, thereby preventing liquids such as moisture and breast milk from entering the receiving cavity 230 through the receiving hole 240 and causing damage to the circuit board 250 and other circuit components.

[0068] Optionally, in the electrical contact direction from the first terminal assembly 130 to the second terminal assembly 220, the projection of the sealing gasket 260 may be located within the projection of the annular sealing portion 50, so that the sealing gasket 260 and the annular sealing portion 50 are mutually offset. In addition, in the direction from the second terminal assembly 220 to the first terminal assembly 130, the sealing gasket 260 does not exceed the contact portion 131 between the second terminal assembly 220 and the first terminal assembly 130, so that the annular sealing portion 50 can directly abut against the housing 211 of the main body 210, so that the annular sealing portion 50 and the sealing gasket 260 can double-seal the interior of the host 20.

[0069] In some embodiments, Figures 2 to 6 As shown, the first terminal assembly 130 may include a fixed covering member 133 and at least two first terminals 134, the at least two first terminals 134 are connected to the heating element 120, and the at least two first terminals 134 are arranged at intervals. The fixed covering member 133 may cover the outer periphery of the at least two first terminals 134, and at least expose the at least two first terminals 134 toward one side of the host 20.

[0070] Among them, at least two first terminals 134 can be fixed by the covering member 133, and the covering member 133 is fixed to limit the at least two first terminals 134, so that the structure of the first terminal assembly 130 is more fixed. In the penetration direction of the through hole 112, the heating element 120 is connected to one end of the at least two first terminals 134, and the other end is electrically contacted with the second terminal assembly 220.

[0071] Moreover, at least one of the limiting groove 132 and the limiting protrusion 1112 can be set on the fixed covering part 133, and it can be correspondingly engaged with at least the other of the limiting groove 132 and the limiting protrusion 1112 set on the outer peripheral wall of the first terminal assembly 130, so as to achieve a close fit with the elastic covering part 111.

[0072] Optionally, the hardness of the fixed covering member 133 is greater than the hardness of the elastic covering portion 111. With such a configuration, the fixed covering member 133 can further support the elastic covering portion 111 and fix the position of the elastic covering portion 111, so that the elastic covering portion 111 is not likely to cause the fixed covering member 133 to deform and separate from each other, and the elastic covering portion 111 and the fixed covering member 133 can be easily assembled and buckled with each other.

[0073] In some embodiments, the fixed covering member 133 is covered by injection molding on the outer periphery of at least two first terminals 134. Injection molding has the advantages of fast molding speed and precise product size. Therefore, injection molding can be used to make the fixed covering member 133 fit closely with at least two first terminals 134, thereby improving the structural tightness of the first terminal assembly 130.

[0074] In some embodiments, the first terminal 134 is arranged in a columnar shape, wherein the columnar arrangement can facilitate the fixing covering member 133 to tightly wrap the outer periphery of the first terminal 134 without easily generating gaps.

[0075] Among them, the first terminals 134 can all be solid copper columns. Using solid copper columns to connect the second terminal assembly 220 of the host 20 and the heating element 120 can prevent moisture from directly contacting the heating element 120 or entering the interior of the host 20, thereby further protecting the breast pump 1.

[0076] In some embodiments, Figures 4 to 7 As shown, the first terminal assembly 130 may include a first power supply positive terminal 1341, a first temperature measurement positive terminal 1342, and a first negative terminal 1343 that are spaced apart from each other, and the first power supply positive terminal 1341 and the first temperature measurement positive terminal 1342 share the first negative terminal 1343. The second terminal assembly 220 may include a second power supply positive terminal 221, a second temperature measurement positive terminal 222, and a second negative terminal 223 that are spaced apart from each other, and the second power supply positive terminal 221 and the second temperature measurement positive terminal 222 share the second negative terminal 223.

[0077] Among them, the first power supply positive terminal 1341 and the second power supply positive terminal 221 are in corresponding electrical contact, the first temperature measurement positive terminal 1342 and the second temperature measurement positive terminal 222 are in corresponding electrical contact, and the first negative terminal 1343 and the second negative terminal 223 are in corresponding electrical contact.

[0078] Optionally, the first power supply positive terminal 1341, the first temperature measurement positive terminal 1342 and the first negative terminal 1343 can all be copper pillars. The second power supply positive terminal 221, the second temperature measurement positive terminal 222 and the second negative terminal 223 can be probes (pogo pins) of the host 20.

[0079] Specifically, with the support of the second terminal assembly 220, the main body 210 can heat the heating element 120 through the first positive power supply terminal 1341 and the first negative terminal 1343, so that the heating element 120 can be gradually heated. With the support of the second terminal assembly 220, the main body 210 can measure the temperature of the heating element 120 through the first positive power supply terminal 1341 and the first negative terminal 1343, so as to obtain the real-time temperature of the heating element 120.

[0080] By setting the first power supply positive terminal 1341 and the first temperature measurement positive terminal 1342 to share the first negative terminal 1343, the setting of one negative terminal can be reduced, thereby reducing the occupied space of the first terminal assembly 130 and the second terminal assembly 220, simplifying the structure of the breast pump 1, and further reducing the difficulty of structural design of the breast pump 1, and also making the appearance of the breast pump 1 more beautiful.

[0081] In summary, the present application sets an annular sealing portion 50 at the connection between the first terminal assembly 130 of the speaker cover 10 and the second terminal assembly 220 of the main unit 20, and sets the annular sealing portion 50 to seal around the periphery of the first terminal assembly 130 and the second terminal assembly 220, so that the connection between the first terminal assembly 130 and the second terminal assembly 220 is in a closed environment, and thus makes it difficult for liquids such as moisture or milk to penetrate into the connection between the first terminal assembly 130 and the second terminal assembly 220 and further enter the interior of the speaker cover 10 and the main unit 20, which can protect the conductive contact between the first terminal assembly 130 and the second terminal assembly 220, and also make it difficult for the speaker cover 10 and the main unit 20 to be short-circuited or damaged, thereby improving the safety of the breast pump 1.

[0082] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
